This 2009 Mazda RX-8 had its factory 13B Renesis two-rotor engine replaced with a Promaz built 20B three-rotor engine. The engine produces 551 horsepower on 16 psi of boost from a Garrett GTX42R turbo controlled by a MicroTech LT16 ECU.

That engine looks to be pretty much at home in that engine bay. Very nice job, and I bet loads of fun…

How much would this set up cost? 20b single turbo in a RX8?

There are many factors that could reduce or raise the price but if everything was purchased “new” I was say $16K-$20K.

Was this engine built using Renesis parts or are they all from RE engines?

Nooooo the engine was produced in the Eunos cosmo 1990-1996 as an option. twin turbo from the factory
